Introduction
HP XP P9000 Performance Advisor interacts with the XP and the P9000 disk arrays through hosts
that have the operating system specific HP XP P9000 Performance Advisor host agents installed.
These hosts form the channel of communication between HP XP P9000 Performance Advisor and
the XP and the P9000 disk arrays. Once the host agents are installed, the corresponding records
automatically appear under the Host Information tab on the Array View screen. The configuration
summary details of the associated XP and the P9000 disk arrays are also displayed on the relevant
HP XP P9000 Performance Advisor screens. If command devices are configured on the XP and the
P9000 disk arrays, the corresponding command device details are displayed for each XP and
P9000 disk array record under the Configuration Data tab on the Array View screen. You can
request an update from a host agent every time you make the configuration changes to the host
agent or their associated XP and the P9000 disk arrays. You can remove records for the host
agents that are no longer connected to the management station.
After the host agents are discovered, start the configuration data collection followed by the
performance data collection for an XP or a P9000 disk array using its corresponding command
device. The configuration data collection can be a one-time activity or scheduled periodically on
a daily, weekly, or a monthly basis. It can be collected using the outband mode of data collection.
During a scheduled configuration data collection, the data pertaining to the new components are
automatically included in the latest configuration data. During a one-time configuration data
collection, the data on new components cannot be collected after the configuration collection is
complete. You must perform another one-time configuration data collection to receive the updated
configuration data.
IMPORTANT: HP XP P9000 Performance Advisor v6.0 supports only the outband mode of
configuration data collection. If you select the HP XP P9000 Performance Advisor Management
Station 6.0 does not support the inband mode of configuration data collection check box while
installing or upgrading from any previous version to v6.0, the schedules that are created using the
inband mode of data collection are deleted.
After the configuration data collection is complete, start the performance data collection by creating
schedules and including components that need to be monitored. You can collect performance data
for the RAID groups, DKCs, ports, continuous access journals, ThP, and the external RAID groups.
In addition, you can also specify the frequency of collection for each of the selected components.
Further, you can enable a performance data collection schedule to automatically monitor and
collect the performance of new components (RAID groups and ports). The components discovered
during the scheduled configuration data collection are automatically added to the performance
data collection schedules that are enabled to automatically monitor new components. For more
information, see “Enabling performance collection schedules for automatic updates” (page 64).
Confirmatory records on all the events generated for host updates, configuration, and the
performance data collection activities are displayed on the Event Log screen. To view the Event
Log screen, click Event Log in the left pane. For more information on managing events, see “Viewing
events” (page 135).
